This section contains the assigned United Nations World Meteorology Organization (WMO)
document identifier, the National Weather Service document identifier, the storm type and name, advisory number, the issuing center
(in this case the NHC), and the date and time for the advisory, and a tropical
cyclone identifier (the format is BBNNYYYY, BB=Basin (AL=Atlantic,
EP=Eastern Pacific), NN=sequence number, YYYY=year).

AT 11 AM EDT...1500 UTC...A HURRICANE WATCH IS IN EFFECT FROM LITTLE
RIVER INLET SOUTH CAROLINA TO CHINCOTEAGUE VIRGINIA...INCLUDING THE
PAMLICO AND ALBEMARLE SOUNDS...CHESAPEAKE BAY SOUTH OF NORTH BEACH
MARYLAND...AND THE TIDAL POTOMAC. A HURRICANE WATCH MEANS THAT
HURRICANE CONDITIONS ARE POSSIBLE WITHIN THE WATCH AREA...GENERALLY
WITHIN 36 HOURS.

HURRICANE WARNINGS MAY BE REQUIRED LATER TODAY OR TONIGHT.

AT 11 AM EDT...A TROPICAL STORM WATCH IS IN EFFECT SOUTH OF
LITTLE RIVER INLET TO SOUTH SANTEE RIVER SOUTH CAROLINA. A
TROPICAL STORM WATCH MEANS THAT TROPICAL STORM CONDITIONS ARE
POSSIBLE WITHIN THE WATCH AREA...GENERALLY WITHIN 36 HOURS.

A TROPICAL STORM WATCH MAY BE REQUIRED NORTH OF THE HURRICANE WATCH
AREA LATER TODAY OR TONIGHT.

Watches/Warnings and News Section

This section contains important news as well as any Watches and/or Warnings
(hurricane and/or tropical storm) that have been issued or discontinued for
coastal areas.

HURRICANE CENTER LOCATED NEAR 27.4N 71.2W AT 16/1500Z
POSITION ACCURATE WITHIN 20 NM

Storm Location Section

This section contains the location of the storm center in latitude and
longitude with the issuance date/time of the product
and an estimate of the accuracy, in nautical miles,
of the position based on the type, quality, and resolution of the fix
platform used.

This section details the current motion of the storm in knots or nautical miles per hour
(1 knot = 1.15 mph), with the direction expressed in terms of 16 compass
points and to the nearest 5 degrees (true) of azimuth (e.g.
360°=North, 90°=East, 180°=South, and 270°=West).

This section gives the minimum central pressure of the storm in millibars.
Whenever a storm is only
threatening the U.S., the wind speed in km/hour is usually discontinued.
Although central pressure is not a hazard it can sometimes be an indicator of future
changes in intensity. Strengthening oftentimes follows a decrease in
pressure while weakening generally follows an increase in the pressure.

REPEAT...CENTER LOCATED NEAR 27.4N 71.2W AT 16/1500Z
AT 16/1200Z CENTER WAS LOCATED NEAR 27.0N 71.0W

Repeat Section

This section repeats the current center location and the location from the last
advisory as a check against transmission errors and to assist mariners in
charting the storm's movement. This section also contains the actual
location of the storm 3 hours prior to the time of the advisory (in
this case, the center at 1200Z or 8AM EDT / 7AM CDT on the 11th
was 27.0°N 71.0°W).

This section gives the 12-hour forecast for the tropical cyclone's position,
the maximum sustained wind and gusts, and an estimate of the size of the wind field using the
same threshold wind values as in the
Wind and Wave Radii section. As before, the
map coordinates of the wind field are compass directions and radial distances
out from the center of the storm in nautical miles.

This section gives the 24-hour forecast for the tropical cyclone's position,
the maximum sustained wind and gusts, and an estimate of the size of the wind field using the
same threshold wind values as in the
Wind and Wave Radii section. As before, the
map coordinates of the wind field are compass directions and radial distances
out from the center of the storm in nautical miles.

This section gives the 36-hour forecast for the tropical cyclone's position,
the maximum sustained wind and gusts, and an estimate of the size of the wind field using the
same threshold wind values as in the
Wind and Wave Radii section. As before, the
map coordinates of the wind field are compass directions and radial distances
out from the center of the storm in nautical miles.

This section gives the 48-hour forecast for the tropical cyclone's position,
the maximum sustained wind and gusts, and an estimate of the size of the wind field using the
same threshold wind values as in the
Wind and Wave Radii section. As before, the
map coordinates of the wind field are compass directions and radial distances
out from the center of the storm in nautical miles. Please note that 64
knot (hurricane force) wind radii are never provided at this forecast time
period.

This section gives the 72-hour forecast for the tropical cyclone's position,
the maximum sustained wind and gusts, and an estimate of the size of the wind field using the
same threshold wind values as in the previous section. The
map coordinates of the wind field are compass directions and radial distances
out from the center of the storm in nautical miles, as in the
Wind and Wave Radii section. In the example the storm was forecast
to move inland and drop in intensity to tropical storm strength by Day 4.
Please note that 64
knot (hurricane force) wind radii are never provided at this forecast time
period.

This section gives the 96-hour extended forecast for the tropical cyclone's position,
the maximum sustained wind and gusts, and an estimate of the size of the wind field using the
same threshold wind values as in the previous section. The
map coordinates of the wind field are compass directions and radial distances
out from the center of the storm in nautical miles, as in the
Wind and Wave Radii section. Additional notes on track errors are
added for the 96 and 120 hour forecasts. In the example the storm was forecast to
become extratropical as it fell below tropical storm strength.
Due to significant uncertainties, wind radii are never provided for this
forecast time period.

This section gives the 120-hour extended forecast for the tropical cyclone's position,
the maximum sustained wind and gusts, and an estimate of the size of the wind field using the
same threshold wind values as in the
Wind and Wave Radii section. As before, the
map coordinates of the wind field are compass directions and radial distances
out from the center of the storm in nautical miles. In the example the storm was forecast to
become extratropical as it fell below tropical storm strength.
Due to significant uncertainties, wind radii are never provided for this
forecast time period.
